- Application filed May 19, 1968. Serial No. 433,783.

To cllfwhom it may concern.; l

Re it known that l, VILLIAM H. SPENQEP., citizen ofthe United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Reflectors` and Lamp-Receiving Sockets Therefoi'; and I. do

hereby declare the followingr to be a full,

improvements in reflectors; and, the inven-l tion has reference toV a reflec or which is more particularly adapted for use in showcases-and in thel displayl windowsofstores,y and also to a novel method of attaching the lamp-receiving socket or sockets to the reflector without the use of solder. l

The invention has for its y principal object toprovide a novel and simply constructed reflector comprising a doubly lined wiring trough, and the invention has for its further .Object to provide a novel lamp-'receiving socket and novel fastening means connected with said socketfor easily and quickly securing the socket in place without the use of solder or screws.A

Other objects of this invention-not at this;

time more particularly enumerated will be clearly understood from .the following -de tailed 'descriptionof my present invention.

' With the various objects of the present invention in View, the same consists, primarily,

- in the novel reflector provided with a double,-

lined wiring-trogli.

'lhe invention consists', furthermore, in the I va rious Vnovel arrangements and combinations of parts, aswell as in the details of the construction of the same, all of which will be more fully described in the following specification and then finally embodied in the clauses of the claims'which are appended to and which form an essentialpart of this specification.

The invention is clearly illust-rated in the accomp anyingdrawings, in which Figure 1 is a side elevation of ashow-case reflector embodying` the principles of my present invention; Fig. 2 is a bottom view of the reilecti: showing the inner or refiecting surface-portions of the reiiector; and Fig. 3-

is a longitudinal vertical section of the reflector, said section being taken centrally through the wiring-trough, said Figs. 1 and 3 showing tlieposition of the reflector with its opening downward. Fig. 4 is a transverse vertical section, taken on line 4*-4 in Fig. 1.

Fig. 5 is a bottom view-of a double-lined socket-holding or carrying member or element removed from within the wire-carrying trough'of the main reiiector-body or shell. Fig. 6 is a rear face view of the socket-holding or carrying member or element, with a ceiving socketfupon said socket-carryingmember. Fig. 8 is a horizontal sectional representation ofthe lampreceiving socket with the securing or attaching means omitted from said view; and Fig. 9/ is a plan view cf the Asecuring or attaching means. '-Fig. 1,0 is a vertical sectional representation of a lampreceiving socket of la .slightly modified construction, and Fig. 1 1 is a horizontal sectional representation Fig. 10.

Similar characters of reference are eine ployed inall of the above described views, to indicate corresponding parts.

Referring-now to the said drawings1 thc ref,-

erence-character 1 indicates one form of reiiector embodying the principles of my present invention, the' same comprising a suitable ieflectorebody or. shell, which is made from sheet-metal, said shell consisting of a pair of longitudinallly'extending body-mem-- I ybers or elements 2 and 3, preferablyof tlv.:

curved cross-sectional coniiguratinn illus. trated more particularly in Fig. 4v of the drawings, although thesaid elements 2 and 3 may be of any other suitable configuration. Upon their lower marginal edges the said elements 2 and 3 are lapped over so as to provide suitably )acting marginal beads 4. The said. elements 2 and 3 are respectively proyided along their u per longitudinally extending portions with t e preferably angularly disposed side-inemof the parts, indicated in said formed and inwardly probers 5 and 6, said members 5 and 6 being A connected by a back-portion 7 which may be provided ywith suita ly disposedcreW-receiving holes or perforations B.A As shown,

the reflector-'body or shell formed by these' various parts has its two end-portions partially closed by means of suitably secured end-pieces 9, which extend part way upon the ends of the angularly disposed body-members 2 and 3. The, trough-shaped portion of the reflector, formed by the side-members 5 and 6 and the connecting back-portion 7, is provided with suitably shaped end-openings 10 for the insertion of electric light wires into either orboth of the ends of the wiring trough of the reflector-body or shell, 4as will be clearly evident.

As shown in Figs. 3 and 4 of the drawings, the inner surface of'the .connecting backportion 7 is provided with a linin 11 made of metal, said lining being suitab y secured upon the inner surface of said back-portion 7, so as to provide a reinforced or double thickness of metal, and said lining 11 being provided vwith screw-receiving holes or perforations 12, corresponding to and registering with the holes or perforations 8 in the backportion 7, for the reception of suitable'screws i or pins for securing the reflector against the inner surface of the usual molding of a showcase, or for securing-the reflector in any desirable position to any other body.

Suitably disposed clamping ears or tongues 13 and 14 are provided, said'ears or tongues being suitably secured upon the inner surfaces of the parts comprising the reflectorbody or shell, and said ears or tongues being bent into holding engagement over the edgeportions of suitably formed and longitudinally extending reflector-elements or glasses 15. Removably arranged within the trough formed by the side-members 5 and 6 and the back-portion 7, and held in place against accidental displacement from the trough by clamping or retaining ears or 'tongues `16,

' which are also suitably secured upon the inner surfaces of the reflector-body or shell, is a socket-holding or carrying-member, which also serves as a rotector or shield, so as to avoid. any possibi ity of coming in contact with the electric light-wires 'which lead into and are disposed within the wiring trough. The said socket-holding or carrying member consists, essentially, of aiiat face-portion or element 17, andthe longitudinally and downwardly extending sidepieces or members 18, which are arranged at angles, so as to extend toward each other and form the open portion, shown in said Fig. 4

of the drawings. Suitably arranged upon the inner face of said flat portion or element 17, directly between the said longitudinally extending side-pieces or members 18, is 4a metal lining or reinforcing plate-like meinber 19, ,having its end-portions 20 bent over the end-edges of the portion or element 17, substantially as shown, and for the urposes of securing the said plate-like inem er 19 in its fixed position. The said socket-holding or carrying-member is suitably slipped into the trough-shaped portion of the main reflector-body or shell, by arrangimT the longitudinally extending and angularly disposed side-members 18 between the angularly disposed side-mernbers 5 and 6, substantially as shown in said Fig. 4 of the drawings, the said socket-holding or carrying member being retained yin place by the frictional contact between the members 18 and themernbers 5 and 6, and by the clamping or retaining ears 16 which are bent over upon -the iiatfaceortion of the element 17, substantially as illustrated in Fig. 2 of the drawings. When these various parts have thus been assembled, it will be evident from an inspection of said Fig. 4 of the drawings, that a wiringtrough having walls of a double-thickness on all of itsv sides will be the result, so that a wiring-trough will be the result which is perfectly proof.` against 'lire from poorly insulated electric wires; and, while it will be evident that these various parts may be made of sheet-metal of much heavier gage, so as to avoid the linings or doubleA thicknesses. of metal, still, by the arrangement of these linings'or double thicknesses of metal as here illustrated and' described in the foregoing specification, it enables the manufacturer to construct a neater reflector shell, and in less time, owing to the metal being of a thinner gage, whereby it is more readily and more neatly forced into the-desired shapes.

The fiat face-portion or element 17 of the socket-holding or carrying member is formed with an opening 21, preferably of a rectangular shape above which is arranged and secured, in the manner to be presently more fully described, a lamp receiving socket. This lamp-receiving socket comprises a suitably formed sheet-metal shell or body 22, in whichis arranged the usual porcelain connection, not here shown, to which the electric wireswithin the .wiring trough lead and are attached thereto, and to which connection an electric light bulb is attached in the usual and well-known manner.

As shown, the shell or body 22 is of a general cylindrical conformation, being open at its opposite ends and being formed in its sides with spring-,like retaining fingers ,or holding lugs 23 with which the marginal bead-like portion 25 of a closing cap 24 can be brought into se arable holding engagement, as will be c early understood. The enlarged portion 26 of the shell or body 22 lis made with a raised portion 27, pressed out of y of which has been forced a'pair of clamping or holding tongues or'lugs 30, see'Fig. 9 of the drawings, said tongues'or lugs being bent downwardly at right 'angles to the said late, so as to be inserted into and through the registering holes or openings 21 and 28 and then'bent over into holding 'engagement cheap and simple fastening device for attach- 'ing the lamp receivingr socket upon the socket carrying member or trough shield of a reflector oi' the general character herein -set forth, which enables me to locate ,thev lamp-receiving socket. much closer to the v'Socket-carrying member or shield, thus obtaining many advantages in that the reflector-body may be of a smaller cross-sectional area; and, furthermore, the lamps being arranged much closer to the reflector-elements or glasses, better illuminating conditions will result. Il desired, the said plate 29 may be dispensed with, in which case the oppositely located marginal edge-portions which bound `the holel or opening in the depressed portion 27 o the shell or body 22 are l'ormed with retaining or holding tongues 31 as shown 1n Fig. 11 ol the drawings, and which are bent downwz'irdly at right angles so as to be ini sorti-d into and tlirongh the reoisterin holes r s g i or openings 21 and 2S and then bent over into holding enge. gen'ient with the inner surface oi' the socket-carrying member or shield, substantially as illustrated in Fig. of the drawings.

f-Fiom vvthe foregoin description of my resent invention it wi l be clearly. seen that ",fhave devised a simply and cheaply constructed reflector whic is especially adapted forthe' illumination of show cases,'but which may be put to other uses in stores, and artgalleries, or wherever desired; and, further-v more, I have `provided a simple and novel,

y A method and meansfl'or the attaching of lampbe more closely arranged within a rellector` receiving` sockets to a body oi: plate-like member in such a manner, that the socketshell or body will lie'much closer to the surface ol' thel body or plate-like member than is. the case with the-constructions and arrangements of the parts as now ordinarily used,-so that a larger-number of lamps can body or shade,l and the lamps can also be placed closer to the reflector-elements or glassesso-as 'to give better illuminating effects. :l am aware that some changes may be made in the various arrangements and com- -tendlng and angularly disposed body membinations of the devices and parts, as well as shaped present invention as described in the foregoing speciiication and as defined in 'the claims which are appended to said specification.
